Sphygmomanometer with mercury manometer

The invention relates to a blood pressure meter with a mercury manometer, which comprises in a housing a mercury container and an exchangeable measuring tube, of which The lower ends with the mercury container detachably

connected and the upper is surrounded by a spring-loaded cap which holds the tube and loads it in the axial direction ¹ and thereby creates a tight connection between the first tube end and the container.

Such blood pressure monitors are known at which both the mercury container and the measuring tube are standardized, so that all tubes in their Manufacture with the help of a normal container can be calibrated, so that the tubes of such Sphygmomanometers are freely interchangeable without 4ig accuracy of the BlutdiniokBieBaers. This is ensured by appropriate training of the known blood pressure monitors been that the interchangeable measuring tubes are easily accessible and the user can replace a tube alone if it should have broken during use.

The manometer tube of such blood pressure monitors must be transparent for functional reasons - πττα are usually made of glass. They are therefore relatively fragile and are usually used under conditions that are not optimally secure

for these tubes. A break in the tubes will therefore occur more often and it is therefore particularly important if the user is to use the measuring tubes without can replace special effort independently. Therefore, the invention is based on the object, the smock to improve, which are used to attach the measuring tubes to the convenience, the speed and to improve the security with which these tubes can be replaced.

The KeS tube is used in many known blood pressure monitors in its usual position partially arranged in a groove, so that the mere release of the Pipe ends, not removing the drill acts, j) he user must rather tilt the housing or bring it out of the hat in some other way. These measures often have the consequence that the pipes fall down or that the measuring fluid is spilled will. On the other hand, however, the hat is relatively important in such sphygmomanometers because it partially encloses the pipe and thereby protects the pipe against frequent contact, which would otherwise seriously endanger the pipe. At the same time, the! Tut ensures sufficient visibility

field created for monitoring the pipe.

The invention is also intended "for such blood pressure monitors, in which the Keßrohr is arranged in a groove, the easy removal of one to be replaced Enable pipe. The invention consists in that a in the area between the hands of the Measuring tube on the outer surface of the tube pressing, spring-loaded member is provided, which the tube after lifting the cap at least partially out of the housing, in particular pushing the hat out. In a preferred embodiment of the invention, the sprung member can be from one in the housing vertical söä Röhr TrejfsehiSwb & jT gsl & gsrt ^ s, vcn

he spring loaded pin -be formed.

As already mentioned, in the case of the blood pressure meter according to the invention, a spring loaded one exercises Cap "which is adjacent to and engaged with the upper end of the measuring tube, usually on the upper end of the measuring tube exerts an axial force, making them mercury-tight connections on both

Manufactures ends of the pipe. When this cap aage- is lifted to remove the ends of the measuring tube from the

To free the holding force, the ejection device urges the Kohr out of the housing and especially the groove in a more accessible position. The user can then the part protruding from the housing

is

of the Hohres and it / no longer necessary, remove the ear from the housing3 by tilting or shaking it after it has been released. By The invention is therefore an improvement of the known blood pressure meter created by the the usefulness of this sphygmomanometer is significantly increased.

Further details and configurations of the invention can be found in the following description, in which the invention is described in more detail with reference to the embodiment shown in the drawing and is explained ο It shows:

3? Ig. 1 is a perspective view of a blood pressure

according to the invention,

Pig. 2 shows the blood pressure meter on an enlarged scale, partly in side view and partly in section after 3? 1 and

3 shows a longitudinal section through the ropes of the blood pressure knife which are essential for the invention according to FIG. 1 on a further enlarged scale.

Fig. 1 shows the blood pressure meter according to the invention in assembled condition. In the housing 1, the measuring tube 2 is attached at its ends, Bas measuring tube is essentially the front of the housing 1 arranged and partially embedded in a groove 3.

Fig. 2 shows the arrangement of the measuring tube 2 in relation better recognize the entire device. Fig. 3 shows details of the ejection device according to the invention. The measuring tube 2 is shown in its normal position. It essentially extends in Extension of the axis of the fastening device and is between the connection point 4 at the the tube is connected to the mercury container and the spring loaded cap 5 is held. In Fig. 3, the cap 5 is shown in the raised position, although it is by the spring 7 to Holding the tube 2 constantly pulled down

will. The cap 5 is raised to release the tube 2 by turning the release lever 9, which is rotatably mounted in the housing 1. In the in Pig. 3 the position shown below engages the lever 9 the flange 10 of the bracket 6 on which the "cap 5 is attached and the spring 7 engages. The lever 9 normally assumes the position 9a shown in phantom, in which the bracket 6 is released by the lever 9, so that the cap 5 under the force of the spring 7 on the upper land of the Measuring tube 2 rests.

In a bore 24 of the housing parts 11 and 22, an ejector pin 20 is slidably mounted, its the end facing away from the measuring tube 2 is loaded by a leaf spring 21, so that the other end this pin under the pressure of the spring 21 on the outer surface of the measuring tube 2 between its ends is applied. If the cap 5 is now lifted and the upper end of the measuring tube 2 is thereby released, it is urgent the spring-loaded pin 20 the tube 2 in the dash-dotted line position 2a, in which the tube effortlessly Throwing grabbed for replacement, can .. The housing is designed so that the upper end of the

Tube 2 with a considerable distance 13 the leading edge of the Geliäusedeckels can happen.

It goes without saying that the invention is not limited to the exemplary embodiment shown, ., ^ but deviations from this are possible without the To leave Kalmen of the invention. In particular, it is possible to use the device for lifting the To couple cap 5 with the device for ejecting the measuring tube so that the hot tube between its ends is only loaded when the cap is lifted from the upper end of the tube. Further Deviations from the illustrated embodiment can result in particular from that in embodiments of the invention only some of the features of the invention for themselves or several can be used in any combination.
